Hong Kong has many monuments which need proper preservation. In accordance with the Antiquities and Monuments Ordinance, the Antiquities Authority may, after consultation with the Antiquities Advisory Board and with the approval of the Chief Executive, by notice in the Gazette, declare a place, building, site or structure as a monument. The Antiquities Authority is then empowered to prevent alterations, or to impose conditions upon any proposed alterations as she/he thinks fit, in order to protect the monument. Up to now, there are a total of 114 declared monuments in the territory.
